Is Jesus the God of the Old Testament?

John, you quote Jesus as saying that the whole of the Torah is in force. However Paul was clear that the new covenant replaced the old covenant and forbid Christians from circumcising Gentiles. Circumcision was the sign of the old covenant given to Abraham before the Ten Commandments. Was Paul wrong? How do you reconcile these two parts of the NT.

Of course Jesus did change the Torah. He said it was alright to “work” on the Sabbath, if it is good work. Jesus forgave the woman caught in the act of adultery instead of having her stoned to death under the law.

Christians uphold very few rules of the Torah. Are you the exception? Are you starting a new sect or what? If not, why not?
